Edit: I want to be clear. I agree with your point, but observing the obvious roadblock to implementation.
There are a lot of companies that make a ton of money off of having more people in prison. Maybe we should just tax them.
In any case, I think it's important to realize we cannot let widespread Constitutional violations go unchecked. It's not that there's no money. The real problem is that there are so many entities profiting from this unjust system that no one bothers to look for solutions in the first place.
If you actually have so many people committing crimes that there are actually too many guilty people for the courts to properly try, you have a societal engineering problem, not a courtroom efficiency problem - you need to get people to stop committing those crimes in the first place, since clearly the justice system isn't working as a deterrent. There are lots of options, including changing social conditions, reclassifying the behavior at issue as not a crime, etc.
Let's talk about race. When a white supremacist wants to kills some folks, sure, that's a problem and we should try to detect, prevent, mitigate, and punish (in that order) their actions.
However, the real issue to solve at a higher level is the societal engineering one where large segments of the population feel a need to turn towards white nationalism. Note: I don't mean "let's make thoughtcrime a thing". I assume the issue is that racially homogeneous rural areas end up with a combination of little welfare and little economic opportunity.
In the medium/long-run, these sorts of issues require UBI, an improved education system, public transportation, and universal healthcare of some sort. That's a tall order and hard sell, so we're left demonizing individuals (treating symptoms).
Very few go to trial because of false-carrots-on-a-stick plea deals to throw someone away without the trial, because the prosecutors know the trial may not go for them.
I wonder if it could be argued that plea deals deprive a citizen of their right to a speedy trial, and are therefore unconstitutional?
At least the 3rd is still going strong!
As such, there are people in prison for almost a decade without a trial because they couldn't afford bail, see the Riker's Island cases.
This is not what I had in mind and I think this result undermines the social contract people have in mind for this country.
Plea bargains allow the justice system to effectively ignore all those costs and instead push them onto a non-representative subset of society.
We simply can't enforce the laws as written, but it's considered easier to avoid enforcing them than to come up with reasonable laws.
Cost of pleading? Maybe a couple hundred dollars.
Cost of ruining someone's life over a drug charge? Maybe worth tenz of thousands or hundreds of thousands of dollars.

Also, sending innocent people to prison because of please bargains costs a lot of money. It's very possible that having real trials and not sending innocent people to jail is cheaper overall.
Most countries in the world manage to have due process. Also the US is one of the wealthiest countries.
